Description
- This application claims priority to and the benefit of Korean Patent Application No. 10-2005-112592, filed on Nov. 23, 2005, in the Korean Intellectual Property Office, the entire content of which is incorporated herein by reference.
- Liquid crystal displays (LCDs) have been used as the displays in various electronic apparatuses including portable communication apparatuses such as cellular phones or PDA. A window is installed on a case of an electronic apparatus for protecting an LCD by isolating it from the outside. An opening is also formed on the case for exposing the LCD to the outside. In this case, the window is coupled with the opening to form a window assembly for a display, and therefore the LCD is protected while images can be viewed from the outside.
- Hereinafter, a conventional window assembly in a display of a mobile phone will be described in detail, with reference to
FIGS. 1 and 2 . -
FIG. 1 is an external perspective view showing a conventional mobile phone, andFIG. 2 is a schematic view showing a portion of the display shown inFIG. 1 . - As shown in
FIG. 1 , a conventionalmobile phone 1 essentially includes adisplay unit 100 displayed so that users can recognize certain signals; aninput unit 200 for inputting display signals to thedisplay unit 100, and a control unit (not shown inFIG. 1 ) for controlling the input signals of theinput unit 200 and the display signals of thedisplay unit 100. - Referring to
FIG. 2 , thedisplay unit 100 of such a conventionalmobile phone 1 includes acase 110; awindow 130 installed in thecase 110; adisplay unit 150 mounted between thewindow 130 and thecase 110 to be installed inside of themobile phone 1; and backlight unit 170 (so-called “BLU”). - The
case 110 represents the bulk of the appearance of themobile phone 1, wherein a predetermined opening is formed for showing images from thedisplay unit 150 installed inside of thecase 110 to the outside, and astepped part 112 is formed along edges of the opening. - The
window 130 is installed in thestepped part 112 of thecase 110, and is designed to protect thedisplay unit 150, installed inside of thecase 110, from the outer environment. - The
display unit 150 emits display signals by driving of themobile phone 1 so that users can recognize the signals, and is arranged inside to correspond to awindow 130 in the inside of themobile phone 1, namely the inside of thecase 110. - If the

-
FIGS. 3A to 3D are partial schematic cross-sectional views showing various embodiments of a display with a window assembly according to the present invention, andFIGS. 4A to 4H are partial plan views schematically showing various embodiments of an adhesion unit provided on a display unit and a backlight unit in a display with a window assembly according to the present invention. - A display with a
window assembly FIGS. 3A-3D includes adisplay unit 750 for optically displaying predetermined signals; and a backlight unit 770 (BLU) provided on a first side of thedisplay unit 750 to project the light to thedisplay unit 750. Thebacklight unit 770 also has a housing unit for enclosing a portion of a second side of thedisplay unit 750. The second side of thedisplay unit 750 is exposed to awindow member 730. The housing unit has at least onepredetermined protrusion 772 protruding in a direction away from the first side of thedisplay unit 750. Thewindow member 730 is closely adhered to a portion of the housing unit of thebacklight unit 770 and is coupled with at least onepredetermined protrusion 772 of the housing unit. Thewindow member 730 is also closely adhered to the exposed second side of thedisplay unit 750. Referring toFIGS. 3A-3B , an adhesion unit is arranged between thewindow member 730 and the housing unit of thebacklight unit 770 to adhere them to each other. A predetermined opening in thecase 710 is formed so that thewindow member 730 can be inserted, and a predetermined steppedpart 712 formed in one side of the opening edge allows coupling of thewindow member 730 with the steppedpart 712. - As shown in
FIGS. 3A to 3B, a predetermined opening is formed in acase 710, and the opening is formed to display pictures to users. In thecase 710 in which the opening is formed, a predetermined steppedpart 712 is formed along edges of the opening formed thereof, and the steppedpart 712, in these embodiments, are formed entirely along the opening edge. However, the invention is not limited thereto and the stepped part may be formed along a portion of the opening edge. The steppedpart 712 in these embodiments is formed on one side of thecase 710, and awindow 730 is then coupled with the steppedpart 712. Although not shown in the figures, different shapes other than the steppedpart 712 shown may be realized according to desired characteristics, namely if windows are installed on both sides of thecase 710, or if grooves are formed in an inner surface of the opening edge formed in thecase 710 to fix thewindow 730 to the grooves. Thewindow 730 may also be closely coupled with the grooves, and the steppedpart 712 may be entirely or partially formed on the edge of the opening formed in thecase 710. The arrangement of these elements thus depends on the desired characteristics. - The
window 730 is made of materials capable of transmitting light at least over the visible light wavelength, and display signals emitted from thedisplay unit 750 are transmitted through thewindow 730 so that users can recognize the display signals. - The
display unit 750 is installed inside of thecase 710, and is formed to correspond to the opening andwindow 730 of thecase 710 so that it can emit display signals for users to recognize. Thedisplay unit 750 may be a liquid crystal display (LCD) composed of liquid crystals or any other suitable display device, such as are used for other applications. - The first side of the
display unit 750 is provided close to one side of thewindow 730. Thedisplay unit 750, more specifically a circumference of thedisplay unit 750, is smaller than or the same size as a circumference of thewindow 730 which closely adheres to thedisplay unit 750. In thedisplay unit 750 and thewindow 730, which are closely adhered to each other, circumferences of each of the closely adhered surfaces precisely correspond to each other upon closely adhering to each other if they have the same circumferences. Center points of thedisplay unit 750 and thewindow 730, in this embodiment, are in agreement with each other for each circumference upon closely adhering to each other if a circumference of thedisplay unit 750 is smaller than that of thewindow 730. - In order to display the display signals from the
display unit 750, abacklight unit 770 is provided at a surface of thedisplay unit 750, more specifically at a surface to which thedisplay unit 750 is closely adhered, and therefore the light at least over the visible light wavelength may be projected into thedisplay unit 750. The surface of thedisplay unit 750 adhering to thebacklight unit 770 is on an opposite side as the surface of thedisplay unit 750 adhering to thewindow 730. - The
backlight unit 770 has a housing unit, and, in this embodiment, thedisplay unit 750 is shaped as a rectangular hexahedron with outer surfaces. One outer surface is closely adhered to thewindow 730 and another outer surface is adjacent to thebacklight unit 770. - The housing unit of the
backlight unit 770 is closely adhered to at least one of the surfaces of thewindow 730, which is not closely adhering to thedisplay unit 750. The side of thewindow 730 that adheres to thebacklight unit 770 also closely adheres to thedisplay unit 750 if a circumference of the adhering surface of thedisplay unit 750 is smaller than a circumference of the window. - A circumference of the
window 730, in this embodiment, is greater than a circumference of the adhering surface of thedisplay unit 750. The circumferential surfaces of thewindow 730 that are peripheral to the adhering surface of thedisplay unit 750 are closely adhered to the housing unit of thebacklight unit 770. That is, in this embodiment, the surface area of thewindow 730 is identical to the sum of the surface area of thedisplay unit 750 and the surface area of the adhering surface between thewindow 730 and the housing unit of thebacklight unit 770. - The housing unit provided in the
backlight unit 770 may be variously modified according to its desired rigidity and functions, and therefore it is shown in the accompanying drawings of this specification without distinction of thebacklight unit 770. - When the
display unit 750 and thewindow 730 enclosed by the housing unit of thebacklight unit 770 are closely adhered to each other, an adhesion unit is provided between thewindow 730 and the housing unit of thebacklight unit 770 so that thewindow 730 and the housing unit of thebacklight unit 770 can be closely adhered to each other. In this embodiment, the adhesion unit is atape 790, but it may be any other element suitable for adhesion. - The
tape 790 provided between thewindow 730 and the housing unit of thebacklight unit 770 may be formed in a surface where the housing unit of thebacklight unit 770 is closely adhered to the window 730 (FIGS. 4A to 4H) so that the tape's 790 outer dimension can be smaller than (FIGS. 4A, 4B , 4E, 4F) or identical to (FIGS. 4C, 4D , 4G, 4H) that of the housing unit of thebacklight unit 770. Thedisplay unit 750 forms a predetermined open or closed opening so that display signals displayed by thedisplay unit 750 can be recognized by the users by means of thewindow 730 and the opening of thecase 710, as shown inFIGS. 4A to 4H. - In this case, a gap g7 is formed between the
window 730 and thedisplay unit 750, and the gap g7 may have a smaller value than a gap g1 in aconventional display 100 shown inFIG. 2 . - As shown in FIGS. 3B and 4A-4H, the
tape 790′, 791-797 provided between thewindow 730 and the housing unit of thebacklight unit 770 may be formed over the surface where the housing unit of thebacklight unit 770 is closely adhered to thewindow 730, as well as the surface where thedisplay unit 750 is closely adhered to the window 730 (FIGS. 4A, 4B , 4C, 4H) and its outer dimension can be smaller than (FIG. 4A ,FIG. 4B ), or identical to (FIG. 4C ,FIG. 4H ) that of the housing unit of thebacklight unit 770. Thedisplay unit 750 forms a predetermined open or closed opening so that display signals displayed by thedisplay unit 750 can be recognized by the users by means of thewindow 730 and the opening of thecase 710. - In this case, a gap g7′ is formed between the
window 730 and thedisplay unit 750, and the gap g7′ may have a smaller value than a gap g1 in aconventional display 100 shown inFIG. 2 . The gap g7′ may have a higher value than the above gap g7 according to thickness of thetape display unit 750 and thewindow 730. This larger gap may have advantages considering the rigidity of the display. - Generally, for the
window 730, thedisplay unit 750 and the housing unit of thebacklight unit 770, each having a rectangular shape, thetape FIG. 4C ,FIG. 4D ,FIG. 4G andFIG. 4H ) on the surfaces where the housing unit of thebacklight unit 770 is closely adhered to thewindow 730, or the housing unit of thebacklight unit 770 and thedisplay unit 750 are closely adhered to thewindow 730. Namely, a circumference of the tape is formed so that its outer dimension can be identical to that of the housing unit of thebacklight unit 770 and/or thewindow 730. The circumference of thetape 790′, 792, 794 may also be formed to correspond to opposite sides of thedisplay unit 750 having a rectangular shape, as shown inFIGS. 4A, 4C , and 4E. Thetape backlight unit 770 having a rectangular shape, as shown inFIG. 4D ,FIG. 4G andFIG. 4H . Thetape backlight unit 770, as shown inFIG. 4B andFIG. 4F . - As shown in
FIGS. 3C and 3D , thewindow 730′ has a steppedpart 732 so as to correspond to the steppedpart 712 formed in thecase 710, and therefore it may be designed to fill the opening of thecase 710. - The
case 710 may have an inward steppedpart 712, and have an outward. stepped part (not shown). Thewindow 730′ provided in the steppedpart 712 according to each modified embodiment also has a steppedpart 732 so that it can fill the opening of thecase 710 with a shape corresponding to thewindow 730′, and the steppedpart 712 of thecase 710 may be a more complicated steppedpart 712 in addition to the steppedpart 712 as shown in the figure. At this time, the steppedpart 732 of thewindow 730′ may be also complicated to correspond to thewindow 730′. - The
tape display unit 750 and thewindow 730′, as shown inFIG. 3C andFIG. 3D . In this case, thetape tape 790′ provided between thebacklight unit 770 and thewindow 730′ can be further extended between thedisplay unit 750 and thewindow 730′. - In the modified embodiments of each
display window display unit 750, and the gaps g7, g7′ have a smaller value than the gap g1 in theconventional display 100 as shown inFIG. 2 , and therefore it is possible to make the display thinner, and the display may be easily assembled by closely adhering thewindow backlight unit 770 to each other, or adhering the housing unit of thebacklight unit 770 and thedisplay unit 750 to each other using atape 790′, 790-797. Accordingly, the display may be more easily assembled when compared to theconventional display 100 since an adhesion space is. easily secured, and therefore its entire cost may be reduced. - Referring to
FIG. 3A toFIG. 3D , apredetermined protrusion 772 is provided on the housing unit of thebacklight unit 770, and theprotrusion 772 is formed in a direction of the exposed side of thedisplay unit 750, namely toward a surface of thewindow display unit 750, and then plays a role to guide thewindow window backlight unit 770. -
